"He wasn't overly impressed with the issue being taken to the C-word, as opposed to the death threats that my family and I were facing," Ms Davidson told The AM Show on Monday.

"He was very angry at the focus on me saying the word, as opposed to the death threats."

According to a recent survey by the Broadcasting Standards Authority (BSA), c**t is the least acceptable of all swear words - at least when it comes to broadcasting it on TV or radio. It's followed by n****r, Jesus f***ing Christ, c***sucker and motherf***er.

The equivalent C-word for men - c**k - was 18th in the 31 words the BSA sought opinions on.

Ms Davidson said she had no regrets using the female C-word word in public at an event where children were present, even her own, because she says it's important for children to understand that kind of abuse is not acceptable.

"The C-word is supposed to shock - that's why when women receive it alone, the best thing we can do is share it and come together and say we reject that public online abuse."

While she wouldn't promise to stop using the word in private, its days of being aired publicly are over.

"I won't need to use it again. I've made a very clear point. I've had incredible international positive reaction, as well as from the people who were there at the rally."

Ms Davidson's use of the C-word was condemned by National MP Paula Bennett and Deputy Prime Minister Winston Peters.

The incident was covered internationally, with articles in the Washington Post, Sydney Morning Herald and the UK's Guardian.
